Description

FIELD OF THE INVENTION

The present invention relates generally to exercise devices, and more specifically to exercise devices providing variable resistance when performing a wide variety of training movements.

BACKGROUND

Various types of exercise machines and devices are well known in the art. The present marketplace includes neck systems, back systems, shoulder machines, pulleys, weights, cams and other devices. Products include Nautilus®, Cybex®, and free weights, among others. There are barbells, dumbbells, bands, tubing, multi-neck machines, and multi-hip machines. Many of the systems are reputable and of good quality, and would most certainly be of benefit to the user.

Many known exercise devices includes resilient elastic cables to provide resistance to motion. Such an exercise device are particularly useful in that, as contrasted with barbells and dumbbells, substantial resistive forces can be generated by a relatively lightweight, portable device. A principal drawback to elastic cable exercise devices, however, is the difficulty encountered in attempting to adjust the restoring force. For example, U.S. Pat. No. 4,779,867 to Hinds discloses an elastic cable exercise device comprising a cable having stirrups at each end and a bar that engages the central portion of the cable to provide a handle for the user to pull against the cable. Hinds discloses that the effective free length of the cable is adjusted by wrapping the cable about the ends of the bar. The assembly in U.S. Pat. No. 5,626,546 issued to Little invokes a wall mounted guide rail framework comprising aperture engaging pins and spaced apertures along the sides for tethering height adjustment, simple channel engagement pins secured by cotter pins, as well as handgrips, pulleys and elastic cords. U.S. Pat. No. 5,176,602 issued to Roberts also employs handgrips, pulleys and elastic cord as do the foregoing. While the patent focuses upon door stop or door impingement tethering, instructions are included therein to mount a rigid framework comprising spaced apertures upon the walls in the corner of a room, the apertures providing tethering points for apparatus connecting links. U.S. Pat. No. 4,848,741 issued to Hermanson illustrates a special framework upon which several pulley wheels are mounted in a selected pattern which permits lengthening or shortening the elastic cord to vary the tethering tension.

Therefore a need exists for a portable, lightweight, foldable apparatus with easily adjustable tension settings and is suitable for performing wide variety of exercises. A further need exists for an exercise device that utilizes bodyweight resistance to assist in performance of exercises. Such an apparatus can assist a user who cannot sufficiently perform exercises without assistance. Such an apparatus is especially adaptable and useful to individuals who may be handicapped or undergoing physical rehabilitation and the like.

The apparatus and methods of the invention will be understood and appreciated further from the following description in connection with the drawings. Other systems, methods, features, and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present invention.

SUMMARY

The exercise apparatuses are lightweight and portable exercise devices for general physical fitness and exercise. Embodiments of exercise devices of the present invention utilize bodyweight resistance to assist in performance of exercises to develop muscle endurance, strength and reduce body fat. Such devices assist in exercising a variety of muscles from hips to shoulders. Overall, the device helps to control movements, transfer energy, shift body weight and move in any direction with ease to assist in performance of exercises, including, but not limited to pushups, pull-ups, dips and squats. It will be appreciated that the method and exercise apparatus of the invention can be used with a minimum of instruction to yield a maximum of controlled exercise. Operation of the apparatus is intuitive and automatic. Having selected appropriate tension elements, the user simply inserts a limb extremity into the apparatus, rests the limb upon a support and secures the limb extremity to a suspended pad. Thereafter, as the user's muscles are strained to move, the apparatus automatically opposes each movement commensurate with the strain in accordance with the force and direction of the strain.

In general the exercise apparatuses comprises a hinged A-shaped frame, seating means, a pulley system elastic resistance bands or cords (tension elements) secured at each end to an anchor device. The resistance imparted by the elastic bands or cords can be easily varied by engaging or disengaging individual resistance bands or lengthening or shortening individual bands. A list of suitable resistance bands includes but is not limited to, springs, springs with rubber coverings, elastic cords, resilient cords, “bungee” cords, Thera-Band® tubing and the like. Certain embodiments also comprise movable gripping means in the form of handles, handgrips and the like, which are attachable to and removable from the ends of the elastic resistance band(s) by the rings, hooks, ball-collar attachments etc. to secure such gripping means to the ends of the elastic. The devices are versatile enough to allow the user to employ a wide range of different type handles in order to achieve the desired exercise effect. The exercise apparatuses can be used to exercise all areas of the spine as well as every major extremity joint from shoulders, elbows, and wrists to hips, knees and ankles without the need for rotating to different machines to exercise different body parts.

The exercise devices of the present invention include devices employing a plurality of elongate elastic tension means such as elastic cables to provide a restoring force and a gripping means removedly attachable to any of the plurality of elongate elastic tension means. The elastic elongate elastic tension means are also selectively attachable to a retainer assembly to provide a wide range of variation in restoring force exerted against the gripping means. The plurality of elongate elastic tension means may also be enclosed in a flexible sheath to prevent the unattached, inactive elastic elongate elastic tension means from becoming entangled with each other or with the attached, active elastic elongate elastic tension means. A list of such elongate elastic tension means includes, but is not limited to, from the group consisting of elastic cables, elastic cords, coil springs, springs, springs with rubber coverings, resilient cords, bungee cords and combinations thereof.

Certain embodiments of the apparatus comprise multiple adjustable elastic bands as elastic elongate elastic tension means the ends of which are removedly attachable to the frame of the device wherein, the number and bands as well as the resistance of each band is varied by a user. The ends of the elastic bands extend through the pulleys (rollers) such that they are disposed on opposite sides of the pulley (roller) axes. The user may attach the required number of elastic bands for a particular exercise to the cushioned assistance seat (seating means). Padded handles are removedly or permanently attached to one end of each elastic band. Such handles allow for proper hand positioning and assist a user in performing various exercises. Handles are easy to grip and an overall padded design makes the unit both comfortable and durable. The apparatuses are also easy to pack-up, fold and store away.

In certain embodiments the seating means is rotatably attached to the cross bar.

In all of the various embodiments of the apparatus the elastic cords can be individually coupled to or detached from the frame such that the overall tension (resistance) of the apparatus can be easily varied to accommodate a variety of exercises and be customized according to the needs of the user. In embodiments such as apparatus 10 as is clearly depicted in FIG. 10, to the distal ends of elastic cords 71, 72, 73, 74, 75 and 76 comprise spherical elements 81, 82, 83, 84, 85 and 86 respectively, wherein each spherical elements has a diameter larger in than that of the chord to which it is attached. Attached to the frame legs 31 and 32 are U-shaped elastic cords retaining elements 95 and 96 each comprising three U-shaped collars having diameters equal to or larger than the diameters of the elastic cords 71, 72, 73, 74, 75 and 76 inserted therein, but smaller than the diameters of the spherical elements 81, 82, 83, 84, 85 and 86, such that the distal ends of elastic cords 71, 72, 73, 74, 75 and 76 are retained when inserted therein. Additionally the attachment of the elastic cords retaining means 95 and 96 to the frame legs 31 and 32 is such that the positions of the retaining means 95 and 96 can be varied along the longitudinal axes of the frame legs 31 and 32 to which they are attached, such that the tension of the elastic cords 71, 72, 73, 74, 75 and 76 can be varied and adjusted. FIG. 10 illustrates such positional variance of the elastic chord retaining element 91 along the longitudinal axis of frame leg 31, wherein an upper position is depicted and a lower position is depicted in phantom by dashed lines and is denoted as (91 a). FIG. 1 also illustrates the apparatus 10 having handgrips 97 and 98, which are removedly attached to the distal ends of elastics chords 71 and 74 respectively.
